Description

 The method relates to the field of medicine and medical technology and can be used for antibacterial ultrasonic treatment with drugs of any skin inflammatory processes.

 Such solutions are known in medicine. Their common drawback is the complexity and inconvenience in sterilizing the concentrator and supplying a drug substance thereto, as well as the high cost. In the existing analogue of RU 2118904, expensive dispensers or inconvenient, bulky drip systems are used to supply the drug substance to the concentrator, and sterilization is achieved by autoclaving, which is very inconvenient because of the long time intervals, because sometimes, for example, in ENT departments, it is necessary to provide continuous processing of the pharynx in the flow of patients.

 In the prototype SU 1801017, the supply of the drug substance is carried out by an expensive and very unreliable ultrasonic dispenser, sterilization is carried out by autoclaving.

 This method is exempted from these shortcomings and allows them to use even the local doctor for calls to the house.

 The objective of this method is to provide a simple, convenient, fast, inexpensive method of sterilizing a concentrator with a simultaneous collection of a medicinal substance in a container (case of a disposable syringe) connected to a concentrator.

The essence of the invention consists in efficient and rapid sterilization of a concentrator having a through axial channel ending with a small diameter hole, and in the collection of a drug substance in a disposable syringe body connected to a concentrator. The concentrator is lowered into a vessel with a wide neck at an angle of 45 ^o to inject about 5 ml of a medicinal substance (chlorhexidine bigluconate) into it for 1 minute.

 This method uses a generator of high-frequency oscillations, an electromechanical converter with an inductor and a hub having a through axial channel connected to a container with a medicinal substance.

 Ultrasound is elastic mechanical vibrations of a dense physical medium with a frequency of more than 20 kHz, i.e. in a supersonic acoustic range of waves that propagate in the form of longitudinal waves and lead to sequential compression and expansion of the medium.

 The drawing shows a method of ultrasonic irrigation with medicinal substances, the principle of the collection of a medicinal substance in a container (case of a disposable syringe) and sterilization.

 What is needed here is a high-frequency oscillation generator 1, an electromechanical converter 2, a hub 3 connected to it with an axial through channel, a container for a drug substance 4 filled with a drug substance 5 (chlorhexidine bigluconate).

The method of sterilization and a set of medicinal substances in a container is implemented as follows. After turning on the generator of high-frequency oscillations 1, the free end of the hub 3, having a through axial channel and ending with a small diameter hole, is lowered into a vessel with a wide neck 6, which is filled with medicinal substance 5 (0.005% aqueous solution of chlorhexidine bigluconate) at an angle of 45 ^o . An angle of 45 ^o is optimal. A smaller angle does not allow you to effectively collect the drug into the body of a disposable syringe, a larger angle will cause the solution to pour out of the body.

 The reverse half-wave of the ultrasonic mechanical oscillation of the concentrator 3 begins to pump medicinal substance 5 into the through axial channel, and from it into the container (case of a disposable syringe) 4. The time (approximately 1 min) is sufficient to fill in the container with the required amount of medicinal substance 5 (approximately 5 ml by one procedure), and the ultrasonic vibrations of the concentrator 3 reduce the time of its sterilization in an antiseptic solution by approximately 100 times.

Practical examples
1. Otolaryngology: Patient M., 26 years old (sore throat prophylaxis) (0.005% aqueous solution of chlorhexidine bigluconate, distance to the dentition 10 cm 1 min per session).

 In this way, pharyngeal ring is irrigated once a month outside the period of exacerbation and 1-2 times irrigation per day at the first sign of disease. The patient noted a significant improvement after treatment.

 2. Dentistry: Patient K., 36 years old. Periodontitis.

 The number of procedures per treatment course 12.4 times a day for 1 minute from a distance of 5 cm to the dentition (0.01% aqueous solution of chlorhexidine bigluconate).

 The patient has clearly observed a decrease in the phenomena of inflammation, pain, swelling, and improvement in epithelization.
